These glitches have been in the game since the 1.9 beta. The first is best showcased on bombers with turrets (BogdanX’s Felixstowe F.2A). It has two turrets: one activated with AG 5, the other with AG 6. To use the one activated by AG 5, I need to activate AG 5 and AG 6.
The other is that the camera always faces 0 degrees north by default
